High power radially polarized light generated from photonic crystal segmented half-wave-plate
P. B. Phua, W. J. Lai, Y. L. Lim +4
We have generated more than 100 watts of radial polarized beam from a Yb fiber laser using a photonics crystal segmented half-wave-plate. We demonstrated the high power handling ca…
A high fidelity approximation of radial polarization conversion
P. B. Phua, W. J. Lai, Yuan Liang Lim
We report a high fidelity (>90%) approximation of radial polarization conversion using a birefringent lens. It offers the advantages of low-cost, easy fabrication, alignment robust…
Polarization Retarder with Cylindrical-Symmetry for Radially Polarized Light
P. B. Phua, W. J. Lai, Yuan Liang Lim
We demonstrate a cylindrically-symmetric polarization retarder for generating exact radially polarized light. It involves an uni-axial crystal whose crystallographic optics axis is…
Ultra-Broadband Radial Polarization Conversion based on Goos-Hanchen Shift
P. B. Phua, W. J. Lai
We demonstrate, for the first time, a scheme that generates radially-polarized light using Goos-Hanchen shift of a cylindrically symmetric Total Internal Reflection. It allows ultr…
